❷ 有关恐龙的专业英语词汇

这两个单词是拉丁文的恐龙名称

Velociraptor是迅猛龙
恐龙体长: 长1.8米

恐龙体重: 不详

恐龙食物: 肉食

生存年代: 白垩纪晚期

生存地点: 蒙古,北美洲

辨认要决: 手三指,脚四趾,其中一个长大爪

恐龙种类: 蜥臀目·虚骨龙类

来历

快盗龙意为敏捷的小偷,快盗龙和恐爪龙很像,但是头较细长。

简介

快盗龙和暴龙、异龙等肉食恐龙相比,只能是小型的肉食恐龙,但是,快盗龙行动非常敏捷,脑容量又大,再加上前后肢均长有非常尖锐的爪子,因此是一种非常具有危险性的极具杀伤力的中小型肉食恐龙。迅快盗龙生有多样利器:头部较大,嘴里有利刃状带锯齿的牙齿;后肢常两趾着地,第三趾上长着长约12厘米,像镰刀一样的利爪,这是它捕杀猎物的重要武器;前肢细长,指上也有利爪,而且灵活,便于抓握。另外,它还有一磁独特的捕杀本领:一只脚着地,另一只脚举起"镰刀",加上前肢利爪的配合,很容易将猎物开膛破肚,一下子置于死地。

1971年,一具完整的快盗龙骨架从蒙古挖掘出来,它是在一场与原角龙生死战争中死去。它长长的前肢插入敌人的头颅,其中一个镰刀状的爪子留在原角龙的肚子体内。

Apatosaurus是雷龙
恐龙体长: 21米 身高: 10米
恐龙体重: 35吨
恐龙食物: 食草
生存年代: 侏罗纪中晚期
生存地点: 美洲
辨认要决: 身体后半部比肩部高,脖子和尾巴差不多长
恐龙种类: 蜥脚类
来 历: 迷惑龙是所有恐龙中最受宠的一群,曾经广为人知的名字是雷龙(brontosaurus)

【名字来源】:
在一亿四千万年前的北美洲丛林,午后时分,翼龙和始祖鸟在树上歇着,偶尔扇动几下翅膀,林中时而传来几声昆虫的鸣叫。突然,传来“轰”、“轰”的声音,由远而近,越来越响,好像雷声一样沉重。然而,天上除漂浮的朵朵白云外,一碧如洗,毫无变天的迹象。晴天打雷,岂不是咄咄怪事!原来这不是天上的雷声,而是丛林里走出了一只大型蜥脚类恐龙。因其脚步沉重,声音巨大,每踏下一步,就发出一声“轰”响,好似雷鸣一般,所以古生物学家给这种恐龙取了一个形象的名字,叫做雷龙,意思是“打雷的蜥蜴”。

【简 介】:
迷惑龙可能是所有恐龙中最受宠的一群,曾经广为人知的名字是雷龙(brontosaurus),今天它失掉这个熟悉的名字,主要因为古生物学家在命名上如此的严谨与吹毛求疵。它可能重量达二十七公吨,而大约体长二十三公尺,它的脖子六公尺长,实际上比体躯还长。它的尾巴大约长达九公尺,它站立到臀部,大约四公尺半高。而它身体后半部比肩部高,但当它以后脚跟支撑而站立起来,它真像是高耸入云。它可能生活在平原与森林中,并可能成群结队而行。它可能受到巨龙(megalosaurus)的攻击而为其假想的猎物。

【雷龙外形及生活习性】:
巨型长脖食草恐龙之一。全长21米,至髋部高4.5米,重约35吨。它们喜欢群体活动,当一大群雷龙从远处走来时,一定是尘土蔽日响声如雷--这就是它名称的由来。这种像肉山一样的大个子,长着一条长脖子和一个很相称的小脑袋。头小身子大的雷龙,一定要花大量的时间来吃东西,而且还很狼吞虎咽。食物从长长的食管一直滑落到胃里,在那儿,这些食物会被它不时吞下的鹅卵石磨碎。雷龙是恐龙中最大的一种,有的身长达30米以上,有6层楼那么高。它们都是食草或树叶的动物。我们在博物馆见到的一些恐龙化石,大多就是这种恐龙。

英语作文:恐龙灭绝的原因

The extinction of dinosaurs The mystery of dinosaur extinction More than 200,000,000 years ago in the Mesozoic, a large number of reptiles living on land, it is also known as the Mesozoic "era of reptiles," the earth was the first to occupy a wide range of vertebrates. At that time the Earth's climate was warmer, all over the dense forests, reptiles have enough food, graally prospered, more and more species. They continued to differentiate into a variety of different types of reptiles, some of today has bee a turtle, and some turned into the type of crocodile, and some turned into today's snakes and lizards, which are a class of Around the world and evolved into today's mammals. All is the dinosaur reptiles in the largest class of physical, very suitable for living in the marshes and shallow lake, when warm, humid air, food is also very easy to find. Therefore, dinosaurs ruled the earth for several million years of time, but I do not know why, in their 6500 years ago a very short period of time of the extinction of a sudden, people see only the left by that time a large number of dinosaur fossils. With regard to the reasons for the extinction of dinosaurs, it is still being studied. For a long time, the most authoritative view, and the extinction of the dinosaurs 6500 years ago about a large meteorite. According to the study, there was a 7-10 km in diameter asteroid will fall on the earth's surface, causing a large explosion, such as throwing a lot of st in the atmosphere to form the Zhetianbiri House of Sand and Fog, led to the suspension of plant photosynthesis , And therefore the extinction of the dinosaurs.

To Pull up the Seedlings to Help Them Grow Once upon a time, an old farmer planted a plot of rice. Everyday he went to the field to watch the seedlings grow. He saw the young shoots break through the soil and grow taller each day. But still, he thought they were growing too slowly. He got impatient with the young plants. "How could the plants grow faster?" He tossed in bed ring the night and could not sleep. Suddenly he hit upon an idea. He had an idea not wait for daybreak. He jumped out of the bed and dashed to the field. By the moonlight, he began working on the rice seedlings. One by one, he pulled up the young plants by half an inch. When he finished pulling, it was already morning. Straightening his back, he said to himself, "What a wonderful idea! Look, how much taller the plants have grown one night!" With great satisfaction, he went back home. He told his son what he had done in a triumphant tone. His son was shocked. Now the sun had risen. The young man was heart-broken to see all the pulled-up young plants dying. People now use " Ba Miao Zhu Zhang" to describe the behavior of those who are too eager to get something done only to make it worse. The idiom is a bit like the English proverb "Haste makes waste" ------to spoil things by excessive enthusia *** . 拨苗助长 从前,有个农夫,种了稻苗后,便希望能早早收成。

每天他到稻田时,发觉那些稻 苗长得非常慢。

他等得不耐烦,心想:“怎么样才能使稻苗长得高,长很快呢? 想了又想,他终了想到一个“最佳方法”,就是将稻苗拨高几分。

经过一番辛劳后,他满意地扛锄头回家休息。

心想:明天稻苗长得一定更高了。

隔天早晨.一早起身,他迫不及待地起去稻田看他的“成果”。

哪知,他跑到稻田时,却看到所有的稻苗都枯萎了。

恐龙的作文【50】字

所有恐龙已经灭绝,但是恐龙的后代——鸟类还是存活下来了,并繁衍至今。

恐龙(英文:dinosaur)是生活在距今大约2亿3 恐龙500万年至6596万年前的并且能以后肢支撑身体直立行走的一类陆生动物,是群中生代的多样化优势脊椎动物,大多数属于陆生(栖息在陆地上)的爬行动物,但能直立行走,支配全球陆地生态系统超过一亿六千万年之久。

恐龙是生活在距今大约2亿3500万年至6500万年前的、能以后肢支撑身体直立行走的的一类动物,支配全球陆地生态系统超过1亿6千万年之久。

大部分恐龙已经灭绝,但是恐龙的后代——鸟类存活下来,并繁衍至今。

另外在口语中,恐龙指丑女。

“恐龙”一词在字典中有两个意思:一类生活在几亿年以前的古动物,现已灭绝;(网络用语)当代相貌不好的女性。

从早侏罗纪到晚白垩纪,恐龙家族适应环境因而发展迅速,使得恐龙向着多样性方向发展,恐龙的种群数目增加,使恐龙这一类具有优势,恐龙由此得以支配地球陆地生态系统。

恐龙种类多,体形和习性相差也大。

其中个子大的,可以有几十头大象加起来那么大;小的,却跟一只鸡差不多。

就食性来说,恐龙有温驯的素食者(吃植物的恐龙)和凶暴的肉食者(吃动物的恐龙),还有荤素都吃的杂食性恐龙.最古老的爬行类化石可追溯至古生代之“宾夕法尼亚纪”(约3亿2000万年前─2亿8000万年前)。

追本溯源,当系由两栖类演化而来。

两栖类的卵需在水中才能开始发育。

爬行类演化出卵壳,可阻止卵中水分的散发。

此一重大改革,使爬行类可以离开水生活。

从2亿4500万年前到6500万年前的中生代,爬行类成了地球生态的支配者,故中生代又被称为爬行类时代。

大型爬行类恐龙即出现于中生代早期。

植食性的迷惑龙,是体形与体重最大的陆栖动物。

棘龙是迄今为止陆地上最大的食肉动物。

另有生活在海中的鱼龙与蛇颈龙及生活于空中的翼龙等共同构成了一个复杂而完善的生态体系。

爬行类在地球上繁荣了约1亿8千万年左右。

这个时代的动物中,最为大家所熟知的就是恐龙。

人们一提到恐龙,眼前就会浮现出一只巨大而凶暴的动物,其实恐龙中亦有小巧且温驯的种类。

恐龙属脊椎动物爬行类,曾生存在中生代的陆地上的沼泽及灌木丛里,后肢比前肢长且有尾。

其中有许多种好食肉,许多种好食草。

其中发展较缓慢的种类,类似最古之鳄及喙头类,发展较完善的种类与鸟类相似。

北京时间10月30日消息,长久以来,古生物学家一直无法确定恐龙是否也像鸟类或者角马等动物一样进行迁徙。

由于可能面临异龙(霸王龙的远亲)带来的威胁,巨型食草恐龙在草原上迁徙并不是一个非常牵强的想法。

现在,美国科罗拉多州大学的研究人员第一次证明,恐龙也会在生存环境恶化时迁徙。

研究人员利用牙齿化石中的氧第一次证明,恐龙在泛滥平原之间迁徙。

在1862年发现的始祖鸟化石,与美颌龙化石极其相似,差别在于始祖鸟化石有明显的羽毛痕迹(美颌龙虽然也有羽毛,但它们很原始),事实上有相当一部分食肉恐龙具有原始羽毛,这显示恐龙与鸟类可能是近亲。

自从1970年以来,许多研究报告指出现代鸟类极可能是兽脚亚目恐龙的直系后代。

现在,大部分科学家视鸟类为唯一幸存发展至今的恐龙,而少数科学家甚至认为它们在生物学中应该分类于同一纲(即现未建成的恐龙纲)之内。

鳄鱼则是另一群恐龙的现代近亲,但两者关系较恐龙与鸟类远。

恐龙、鸟类、鳄鱼都属于爬行动物的初龙类演化支,该演化支首次出现于晚二叠纪,并在中三叠纪成为优势动物群。

从发现恐龙到20世纪前60年,由于对恐龙了解不足,科学家与大众媒体都视恐龙为行动慵懒、缓慢的冷血动物。

但是自从20世纪70年代开始的恐龙文艺复兴,提出恐龙也许是群活跃的温血动物,并可能有社会行为的观点。

近期发现的众多恐龙与鸟类之间关系的证据,支持了恐龙是温血动物的观点。

但事实究竟如何,还需进一步的考证。

实际上,人类发现恐龙化石的历史由来已久。

早在发现禽龙之前,欧洲人就已经知道地下埋藏有许多奇形怪状的巨大骨骼化石。

直到发现了禽龙并与鬣蜥进行了对比,科学界才初步确定这是一群类似于蜥蜴的早已灭绝的爬行动物。

1842年,英国古生学家查理德·欧文创建“dinosaur”这一名词。

英文的dinosaur来自希腊文deinos(恐怖的)Saurosc(蜥蜴或爬行动物)。

对于当时的欧文来说,这“恐怖的蜥蜴”或“恐怖的爬行动物”是指大的灭绝的爬行动物(实则不是)。

实际上,那个时候发现的恐龙并不多。

自从1989年南极洲发现恐龙后,全世界七大洲都已有了恐龙的遗迹。

目前世界上被描述的恐龙至少有650至700多种(生物学上的物种)。

后来,中国、日本等国的学者把它译为恐龙,原因是这些国家一向有关于龙的传说,认为龙是鳞虫之长,如蛇等就素有小龙的别称。

恐龙在地球上生存了近1亿7千万年的时光,在这么长的时间里,的环境也发生了许多变化。

原本连成一整片的盘古大陆逐渐漂移,分裂成为现在我们熟知的形态。

这些地球板块漂移到全球各处后,由于光照不再均匀,热量的传导也被海洋阻断,气候环境也跟着发生了改变。

小恐龙到动物园英文作文

今天,我和爸爸、爷爷、弟弟一起去看精彩的恐龙展。

恐龙展设在儿童公园里,一进儿童公园的大门就看到一张大海报,上面写着“重返侏罗纪”,再往里走会看到一只身材高大的机器蜀龙,再往前走就到了恐龙展的入口处。

进入恐龙展区就看见活灵活现的恐龙机器人,它们的身高和书上描写的恐龙一样大小,好像我们直接进入了侏罗纪公园,耳边不时传来恐龙的恐怖叫声。

那些恐龙的种类有恐龙世界的“高个子”梁龙、背上长着三角形骨板的剑龙、拥有恐怖爪子的恐爪龙……,走着走着我们来到了肉食性恐龙中最凶猛的暴龙展览处,那只暴龙和《侏罗纪公园》这部电影里面的暴龙一模一样,好像它马上就要把我们给吃了。

这些恐龙的皮是用橡胶做的,恐龙旁边放着一个发音盒,恐龙的叫声就是从这个发音盒发出来的。

那些恐龙叫声声音怪异,有时会突然叫得特响,你会被这叫声吓一大跳;有些恐龙的头会藏在树丛间,等你不经意发现时,会吓得你魂飞魄散。

庞大的恐龙家族为什们会消失了呢?据科学家推测:由于地震使大陆分离,各地气候大变,恐龙无法适应,最后灭绝了。

这次恐龙展让我了解了更多恐龙的知识,我希望能进一步发现恐龙的奥秘。

The Sixth Extinction By Niles Eldredge

About 30,000 species go extinct annually.
大约每年有30000种物种走向灭绝。

There is little doubt left in the minds of professional biologists that Earth is

currently faced with a mounting loss of species that threatens to rival the five

great mass extinctions of the geological past.
在生物学专家心中都有一个小小的疑问,地球是否在面临着可能媲美过去五大物种灭绝的另

一次不断增加的物种灭绝。
As long ago as 1993, Harvard biologist E.O. Wilson estimated that Earth is

currently losing something on the order of 30,000 species per year -- which

breaks down to the even more daunting statistic of some three species per hour.
早在1993年,哈佛一名生物学家,E.O. Wilson就预测地球物种正在以每年30000种的速度消

失, 而这种令人心悸的预测则被更为恐怖的每小时3种的统计结果结束了.
Some biologists have begun to feel that this biodiversity crisis -- this "Sixth

Extinction" -- is even more severe, and more imminent, than Wilson had supposed.
The previous mass extinctions were e to natural causes.
一些生物学家已经开始察觉到生物多样性的危机了. Wilson预测说这次的第六次物种灭绝,

比以往五次更为严重,更为紧迫。前几次大量物种灭绝的发生,只是因为自然原因。

Extinction in the past
过去的几次大量物种灭绝

The major global biotic turnovers were all caused by physical events that lay

outside the normal climatic and other physical disturbances which species, and

entire ecosystems, experience and survive. What caused them?
过去的几次生物界翻天覆地的变化,原因都不外乎正常的天气还有其他的物理因素干扰这些

物理因素,而整个生态系统都安然度过了。这些都是怎样发生的呢?

* First major extinction (c. 440 mya): Climate change (relatively severe and

sudden global cooling) seems to have been at work at the first of these-the end

-Ordovician mass extinction that caused such pronounced change in marine life

(little or no life existed on land at that time). 25% of families lost (a family

may consist of a few to thousands of species).
第一次大量物种灭绝(c.440 mya):较为严重的突然全球变冷似乎先发生,然后就有了

引起海洋物种显著变化的后奥陶纪的大量物种灭绝(当时很少或者根本没有生物在大路上生

存),大约25%的物种科目消失了(一个物种科目可能含有几十到上千的物种)。
* Second major extinction (c. 370 mya): The next such event, near the end of

the Devonian Period, may or may not have been the result of global climate

change. 19% of families lost.
第二次大量物种灭绝(c. 370 mya):第二次类似的事件发生在大概泥盆纪结束的时候

,尚未清楚是否由于全球气候的变化。这次有19%的物种科目消失了。
* Third major Extinction (c. 245 mya): Scenarios explaining what happened at

the greatest mass extinction event of them all (so far, at least!) at the end of

the Permian Period have been complex amalgams of climate change perhaps rooted

in plate tectonics movements. Very recently, however, evidence suggests that a

bolide impact similar to the end-Cretaceous event may have been the cause. 54%

of families lost.
第三次大量物种灭绝(c. 245 mya):地质构造论中二迭纪发生的大范围地壳运动和气

候的复杂多变可以解释这次起码到现在为止是最大规模的大量物种灭绝。但在最近,又有证

据说类似于后白垩纪的流星事件可能是这次物种灭绝的主要原因。这次54%的物种科目被灭

绝了。
* Fourth major extinction (c. 210 mya): The event at the end of the Triassic

Period, shortly after dinosaurs and mammals had first evolved, also remains

difficult to pin down in terms of precise causes. 23% of families lost.
第四次大量物种灭绝(c.210 mya):这次大量物种灭绝发生在发生在三叠纪后期,在进

化出恐龙和哺乳动物之后不久。这次物种灭绝很难精确确定出原因。23%的物种科目消失了


* Fifth major extinction (c. 65 mya): Most famous, perhaps, was the most

recent of these events at the end-Cretaceous. It wiped out the remaining

terrestrial dinosaurs and marine ammonites, as well as many other species across

the phylogenetic spectrum, in all habitats sampled from the fossil record.

Consensus has emerged in the past decade that this event was caused by one

(possibly multiple) collisions between Earth and an extraterrestrial bolide

(probably cometary). Some geologists, however, point to the great volcanic event

that proced the Deccan traps of India as part of the chain of physical events

that disrupted ecosystems so severely that many species on land and sea rapidly

succumbed to extinction. 17% of families lost.
第五次大量物种灭绝(c. 65 mya):物种灭绝中最为著名的可能莫过于距离现在最近的

在白垩纪末发生的第五次物种灭绝. 根据对化石的研究发现,在这次物种灭绝中,陆地恐龙和

鹦鹉螺都完全消失. 有着同样命运的还有许多物种谱中的生物. 在过去十年中,大家都认为

这次物种灭绝的原因在于一次(也有可能是多次)地球与宇宙流星(很有可能是彗星)的相撞.

但一些地质学家持不同意见。他们把原因归结于产生了印度德干traps(陷阱?)的火山运

动而造成的生态系统的剧烈变动,最终使陆地上和海里的许多生物迅速走向灭绝。

The current mass extinction is caused by humans.
现在我们面临的大量物种灭绝是人为因素造成的。
How is the Sixth Extinction different from previous events?
第六次大量物种灭绝与之前有什么不同呢?

At first glance, the physically caused extinction events of the past might seem

to have little or nothing to tell us about the current Sixth Extinction, which

is a patently human-caused event. For there is little doubt that humans are the

direct cause of ecosystem stress and species destruction in the modern world

through such activities as:
初步来看,过去五次大量物种灭绝对现在第六次认为造成的物种灭绝没有任何可借鉴意义,

因为毫无疑问人类造成了如下几种情况,给生态系统造成了很大压力,给物种带来了灭绝:

* transformation of the landscape
地貌的改变
* overexploitation of species
物种资源的过度开发
* pollution
污染
* the introction of alien species
带来了外来物种

And because Homo sapiens is clearly a species of animal (however behaviorally

and ecologically peculiar an animal), the Sixth Extinction would seem to be the

first recorded global extinction event that has a biotic, rather than a

physical, cause.
同样由于智人很明显是动物的一员(虽然行为和外貌上不很像动物),第六次物种灭绝似乎

是有史以来第一次由生物而不是物理环境变化引起的。

We are bringing about massive changes in the environment.
我们给环境带来了剧烈的变化。
Yet, upon further reflection, human impact on the planet is a direct analogue of

the Cretaceous cometary collision. Sixty-five million years ago that

extraterrestrial impact -- through its sheer explosive power, followed

immediately by its injections of so much debris into the upper reaches of the

atmosphere that global temperatures plummeted and, most critically,

photosynthesis was severely inhibited -- wreaked havoc on the living systems of

Earth. That is precisely what human beings are doing to the planet right now:

humans are causing vast physical changes on the planet.
Humans began disrupting the environment as soon as they appeared on Earth.
然而进一步的说,人类对于地球的影响,完全相当于白垩纪的彗星撞击。彗星带来了爆炸性

的力量,紧接着把碎片带到大气上层,引起了全球气候降低,还有最重要的,极大地降低了

光合作用,就像是对地球生态系统的愤怒轰炸一样。这完全和现在人类正在对这颗行星做的

一样:人类正在给这颗行星的物理环境带来巨大的改变,而这种改变,自从人类出现便已经

开始了。
What is the Sixth Extinction?
什么是第六次大量物种灭绝?

We can divide the Sixth Extinction into two discrete phases:
我们可以把第六次大量物种灭绝分为两段

* Phase One began when the first modern humans began to disperse to

different parts of the world about 100,000 years ago.
第一阶段开始于100,000年前现代人类分散到世界各地
* Phase Two began about 10,000 years ago when humans turned to agriculture.
第二阶段开始与10,000年前人类开始了农业劳动

❺ 恐龙的资料(英文带中文翻译的)

恐龙简介
恐龙是出现于二亿四千五百万年前,并繁荣于六千五百万年前结束的中生代爬行动物。或为恐龙和与它同一时代的蛇颈龙、翼龙等的模糊总称。恐龙在在6500万年前白垩纪结束的时候突然全部消失,成为地球生物进化史上的一个谜,这个谜至今仍无人能解。地球过去的生物,均被记录在化石之中。中生代的地层中,即曾发现许多恐龙的化石。其中可以见到大量或呈现各式各样形状的骨骼。但是,在紧接着的新生代地层中,却完全看不到恐龙的化石。由此推知恐龙在中生代时一起灭绝了。
恐龙种类多,体形和习性相差也大。其中个子大的,可以有几十头大象加起来那么大;小的,却跟一只鸡差不多。就食性来说,有温顺的 草食者
和凶暴的肉食者,还有荤素都吃的杂食性恐龙。
Dinosaur Profile

Dinosaurs appeared in two hundred forty-five million years ago, and prosperity at the end of the Mesozoic reptiles 65 million years ago. , Or dinosaurs, and with it the same era plesiosaurs, pterosaurs and other fuzzy generic term.
